# Vega: A Visualization Grammar 







**Vega** is a *visualization grammar*, a declarative format for creating, saving, and sharing interactive visualization designs. With Vega you can describe data visualizations in a JSON format, and generate interactive views using HTML5 Canvas or SVG.

For [documentation](https://vega.github.io/vega/docs/), [tutorials](https://vega.github.io/vega/tutorials/), and [examples](https://vega.github.io/vega/examples/), see the [Vega website](https://vega.github.io/vega). For a description of changes between Vega 2 and later versions, please refer to the [Vega Porting Guide](https://vega.github.io/vega/docs/porting-guide/).

Try using Vega in the online [Vega Editor](https://vega.github.io/editor/#/examples/vega/bar-chart).
